Silos are structures that are used for storing different types of granular material. Dynamic behavior of silos under seismic loads is very complex. In this paper seismic behavior of steel silos with different height to diameter ratios is investigated by considering granular material-structure interaction using ABAQUS finite element package. Silo wall is modeled by shell elements and its behavio...

This project utilizes integral calculus to find the exact volume of a non-uniform cylindrical-shaped silo used store wheat and calculate cost material utilized build such silo. Due its shape, is divided into two sections each calculated. The final for with measurements provided approximately 2330.02 meters cubic surface area 1074.96 squared, which considered be large capacity With there are cos...

The advantages of metal silos in comparison with reinforced concrete are given. Types depending on a wall design considered. construction steel spiral-fold and the method forming cylindrical body general silo is illustrated. Features folding lock, its geometry location described. specifics silo, which affects their stress-strain state, analyzed. Listed two calculation schemes silо complexity in...

We formalize our programming model in the context of a typed lambda calculus with records. Figure 1 shows the abstract syntax of our core language. Besides standard terms, the language includes terms related to (a) spores, (b) silos, and (c) futures. The spore term creates a new spore. It contains a list of variable definitions, the spore header, and a closure which may only refer to its parame...

Measurements show that silo wall pressures exhibit large fluctuations in time and space during discharge of the silo. This observation is important for the design of the silo wall because spatial pressure variations may impose substantial bending moments that otherwise may be small or vanishing due to the carrying ability of the membrane forces in the silo wall. Information about the stochastic...

We report experimental observations of sound waves in a granular material during resonant silo discharge called silo music. The grain motion was tracked by high-speed imaging while the resonance of the silo was detected by accelerometers and acoustic methods. The grains do not oscillate in phase at neighboring vertical locations, but information propagates upward in this system in the form of s...
